CROSSTIE FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Oct. 18, 1921.

Application filed April 18, 1921. Serial No. 462,473.

To all whom it may concern: 1

Be it known that we, LOUIS G. MILLER and EDWARD C. LONG, citizens of the United States, and residents of the borough of WVestmont, in the county of Cambria and State of Pennsylvania, whose post-office address is J ohnstown, Pennsylvania, have invented certain new and useful Improvements in Crossties for Railway-Cars; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to make and use the same.

Our invention relates to railway cars, and particularly to the tie-beams or cross-ties for bracing and strengthening the sides of the cars against inward or outward bulging, and it relates also to rolled steel sections for forming such cross-ties.

The object of our invention is to produce cross-ties by a cheap and simple method whereby the distribution of the metal in the cross-section is economical, practical and well adapted to produce the results desired.

A cross-tie that will accomplish the objects outlined must be capable of acting as a tie, a strut and a beam, and it is also subjected to impact from falling lumps of coal, stone or other articles when loading or unloading and must be capable of withstanding the stresses so produced without failure or distortion,either as a whole or in any of its details' Therefore compression, bending and impact stresses are governing features of the design and economy requires a contour and a radius. of gyration compatible with the stresses in- 'duced. The cross-tie is subjected to loads,

especially impact, as above stated, in all directions, during loading, transportation and unloading, so that it should therefore have a large radius of gyration for every axis of the section, and this is provided by our in vention. a

To this end a symmetrical section with the metal properly distributed is essential and therefore we provide a built-up polygonal shaped section composed of two flanged trough-shaped sections riveted together through their flanges. The flanged troughshaped sections may be rolled in various forms, as shown, but one of the outstanding features of each is the thickened central web or central portion'of thetrough whereby an economical distribution of the metal is maintained. The upper and lower edges are also pre'e'minently the made thin or even angular to properly avoid, as much as possible, and resist the impact of the loading. \Ve also provide brackets or connecting members for rigidly securing the cross-ties to the car sides.

Having thus given a general of our invention, we will now, in order to make the matter more clear, refer to the annexed sheet of drawings, forming part of this specification, and in whichlike characters refer to like parts.

Figure l is a vertical transverse sectional elevationof a hopper car body illustrating the application of our invention; Fig. 2 is a side elevation of our crosstie and connecting elevation of one form of cross-tie showing a cast or malleable iron connecting member secured thereto; Fig. 4 is a side elevation of the connecting member or bracket and the end portion of the cross-tie shown in Fig. 3; Fig. 5 is an end elevation of another form of our cross-tie showing pressed metal connecting members secured thereto; Fig. 6 is a transverse section of one form of the cross-tie 011 the line VI-VI of Fig. 2, and Figs. 7 8 and 9 are transverse sections of slightly modified forms of our crosstie.

Referring now to the characters of reference on the drawings: The car-body 1 has the sides 2, to which are. secured the cross ties 3, as shown in Fig. 1'. The crosstie 3 is composed of two flanged trough-shaped members which have the thickened central web or central portion 4, the diagonal webs or inclined sides 5 and the flanges 6, which are provided with short lips 7. Rivets 8 in the flanges 6 secure the parts of the cross-tie to each other, thereby coordinating its structure.

Connecting members 9 are provided with flanges 10 having other flanges 12, which are shaped to fit the cross-tie 3 except at the lips 7, which are cut away as at 14:. The con description members assembled; Fig. 3 is an end necting members 9 are secured to the crosst1e 3 by rivets in the flanges 6 and the rivets 13 in the diagonal webs 5. The flange 10 of the. connecting member 9 is provided with holes 11 and rivets which pass through these through which rivets secure it to the'car side,

the flange 19 of which has an opening 17 that is shaped to fit the cross-tie 3 and is secured thereto by rivets in the flanges 6 and the rivets 18 through the thickened central 7 webs 4 of the flanged trough-shaped section. As shown in Fig. 5 the flange 10 is provided with holes 11 and rivets which pass through these and the sides of the car secure the cross-tie 3 thereto.

Fig. 7 shows a modification 20 of the flanged trough-shaped member and 4 represents the thickened central webs thereof, 5 the diagonal webs and 21 the thickened flanges which are straight and are provided with beveled edges 22. Rivets 23 through the flanges 21 secure the parts of the crosstie together, thereby coordinating its structure.

Fig. 8 shows another slight modification 24 of the flanged trough-shaped member in which 4 represents the thickened central web, 5 the diagonal webs and 25 the flanges which are provided at their ends with lips 26 and beveled outer edges 27. Rivets 28 through the flanges 25 secure the parts of the crosstie together. 7

Fig. 9 shows a modification 29 of the flanged trough-shaped member and 4 represents the thickened central webs, 5 the diagonal webs, 30 one of the flanges and 31 the other flange that is provided with an overlapping lip 32, which has beveled edges 33. Rivets 34 through the flanges 30 and 31 secure the parts of the cross-tie together.

7 It is therefore evident that the construction of our cross tie is such as to secure the maximum strength for the minimum amount of metal and this desideratum is largely accomplished by a design which insures a dis tribution of metal that will givethe greatest strength in all directions. The utility and economy of the design is due to the use of a symmetrically built-up cross-tie composed of two rolled flanged trough-shaped members, the central webs of which are thick ened so as to maintain a large radius of gyration throughout the section. The construction of the cross-tie is such as to enable it to be made cheaper and stronger than pressed. ties or rolled sections heretofore used, and at the same time provide a crosstie that can withstand the impact of falling materials, grab buckets, inertia or movement of cargo producing shocks during transportation, unloading with car-dumpers, etc. Furthermore the shape of our cross-tie is such as to prevent any materials lodging thereon and it presents no projections to catch or foul the loading or unloading apparatus.

Although we have described and illustrated our invention in considerable detail, we do not wish to be limited to the exact and specific details thereof, as shown and described, but may use such modifications in, substitutions for, or equivalents thereof, as are embraced within the scope of our invention, or as pointed out in the claims.

Having thus described our invention, what we claim and desire to secure by Letters Patent is 1. A polygonal shaped cross-tie for railway car bodies comprising two riveted flanged trough-shaped members provided with an integrally thickened central web portion.

2. A cross-tie for railway car bodies comprising two trough-shaped members secured together having a continuous body bent in two different planes, each having in succession an upper flange, an upper diagonal web, a central integrally thickened web, a lower diagonal web and a lower flange.
